INLET PIPE. FOR BOILERS, TANKS, AND THE LIKE.

Application filed July 13, 1928.. Serial No. 292,515.

The present invention relates to an inlet pipe for boilers, storagetanks and the like and has for its prime object to provide a pipewhereby fluid may be injected into a boiler, tank or the like withoutdisturbing the sediment therein.

Another very important object of the in vention resides in the provisionof a pipe or tube leading into a boiler, storage tank or the like andproviding on the inner end of the tube or pipe a closure therefor andslitting the inner end of thc tube longitudinally and providing a sleevethereover, said sleeve bulging outwardly at its intermediate portion andbeing longitudinally slitted, the slits of the tube being offset inrelation to the slits of the sleeve.

A still further very important object of the invention resides in theprovision of novel means for preventing the stirring up of sediment in aboiler which is simple in its construction, inexpensive to manufacture,and thoroughly eflicient and reliable in use.

With the above and. IllllTlGlOUSOtllGl objects in view as will appear asthe description proceeds, the invention resides in certain novelfeatures of construction, alld in the combination and arrangement ofparts as will be hereinafter more fully described and claimed.

In the drawing:

Figure 1 is a sectional elevation of a boiler showing my improved inletpipe associated therewith,

Figure 2 is a longitudinal section through the inner end of the inletpipe, and

Figure 3 is an enlarged transverse section therethrough takensubstantially on the line 38 of Figure 2.

Referring to the drawing in detail it will be seen thatthe numeral 5denotes a boiler, storage tank or the like into which projects an inletpipe 6 preferably from the top end thereof and terminates a distanceabove the bottom thereof. As is well known sediment usually collects inthe bottom of the boiler;

The inner end ofthe pipe 6 is closed as is indicated at 7 andtheportions of the pipe immediately adjacent the closed end '2' are willbe seen that incoming water is caused to be sprayed to the side ratherthan directly downwardly so as not to disturb the sedinent in the bottomof the boiler or storage tank and furthermore the force of the incomingwater is dissipated by the arrangement of the slits 10 in respect to theslits 8 since the tube 9 functions as a battle.

It is thought that the construction, utility and advantages of thisinvention will now be quite apparent to those skilled in this artwithout a more detailed description thereof. 7 1

The present embodiment'ofthe invention has been disclosed in detailmerely for the purposes of exemplification since in actual practice itattains the features of advantage enumerated as desirable in thestatement of the invention and the above description.

It will be apparent that changes in the details of construction, and inthe combination and arrangement of parts may be resorted. to withoutdeparting from the spirit or scope of the invention as hereinafterclaimed or sacrificing any of its advantages. I

Having thus described my invention, what v I claim as new is: I

1. In combination, a boiler, an inlet pipe extending into the boiler,means closing the inner endiof the pipe, said pipe immediately adjacentthe closed end being provided with lol'lgitudinally extending slits, atube over the slitted end of the pipe and having longitudinal slits.

2. I11 combination, a boiler, an inlet pipe extending into the boiler,VIHEZIHS closing the inner end of the pipe,said pipe immediatelyadjacent the closed end being provided with longitudinally extendingslits, a tube over t1i.esli:tte-:l end of the pipe and havinglongitudinal slits, said tube being bulged outwardly from the pipe atits intermediate portion.

3. In combination, a boiler, an inlet pipe extending into the boiler,means closing the inner end of the pipe, said pipe ilnined'b atelyadjacent the closed end being provided with longitudinally extendingslits, a tube over the slitted end of the pipe and having longitudinalslits, said tube being bulged 10 outwardly from the pipe at itsintermediate portion, the slit in the tube being alternately arranged inrespect to the slits in the pipe. In testimony whereof I affix mysignatiu'e.

GEORGE H. GUNDLACH.
